Atrioventricular Septal Defect

Atrioventricular septal defect

Atrioventricular septal defect is an opening between all four chambers of the heart that is present at birth (congenital heart disease). The opening is caused by a failure of heart tissue to come together during the growth of the fetus.

Atrioventricular septal defect results in a large opening in the center of the heart, with a hole between the 2 lower chambers (ventricular septal defect) and between the 2 upper chambers (atrial septal defect).

Atrioventricular septal defect requires surgery to correct.

What can you expect if your newborn has an atrioventricular septal defect?

  • You may see tubes and wires attached to your baby. This can be scary to see. But these things help the doctor treat your baby. The tubes supply air, fluid, and medicines to your baby. The wires are attached to machines that help the doctor keep track of your baby's vital signs. These include temperature, blood pressure, breathing rate, and pulse rate.
  • It may seem that your baby is getting lots of tests. All of these tests help your doctor keep track of your baby's condition and give the best treatment possible.
  • If your baby has trouble breathing, the doctor may use a ventilator. This machine helps your baby breathe. To do this, the doctor puts a soft tube through your baby's mouth into the windpipe.
  • The hospital staff will give your baby the nutrition that your baby needs. The doctor may feed your baby through a soft tube that goes through the nose and into the stomach. Or the doctor may use an I.V. that goes through the belly button to do this.
  • Your baby may need extra oxygen. It is given to the baby through tubes in the nose.
  • After surgery, your baby will need routine checkups to check on the heart. Your baby may need more surgeries or procedures in the future.
  • It's hard to be apart from your baby, especially when you worry about your baby's condition. Know that the hospital staff is well prepared to care for babies with this condition. They will do everything they can to help. If you need it, get support from friends and family. Ask the hospital staff about counseling and support.

How is atrioventricular septal defect treated in newborns?

Your baby may get medicine. It may include medicines given through a blood vessel. This is often done through the belly button.

Your baby will need surgery. The doctor will close the hole with patches that become part of the heart. The heart valves are separated to make them as normal as possible. Your baby will be asleep during the surgery.

The surgery may be done when a baby is a few months old. Your baby will probably be in the hospital during this time. When you can go home with your baby, you'll get instructions on how to care for your baby.

What is atrioventricular septal defect in newborns?

Atrioventricular septal defect is a hole in the center of the heart. The hole is where the four chambers of the heart normally would meet. The opening is caused because the heart tissue did not join together during the growth of the fetus. While this hole is there, blood doesn't flow as well as it should. This can make your baby's heart pump harder.

This is a congenital heart disease. This means your baby was born with it.

Your baby may need special care, such as being in the neonatal intensive care unit (NICU). This may be scary for you. But the hospital staff understands this. They will explain what happens and will answer your questions.
